New South Wales

New South Wales is Australia's most populous state, home to roughly 8.3 million people and the metropolitan engine of Sydney. It stretches from the Pacific coast across the Great Dividing Range into the riverine plains of the Murray-Darling basin, bordering Queensland to the north, Victoria to the south, and South Australia to the west. The state's economy is the country's largest by output, anchored by finance, professional services, tourism, and the freight and logistics corridors that run through Newcastle and Port Botany.

Plates issued in New South Wales follow the post-2013 ABC-12D format: three letters, two digits, and a final letter, e.g. ABC-12D. The current series is administered by Transport for NSW from a black-on-yellow base, with "NSW" set as a wordmark at the bottom of the plate. The yellow background was reintroduced in 2010 after several decades of black-on-white, and the seven-character alphanumeric series followed in 2013 once the preceding ABC-123 combinations approached exhaustion. Older ABC-123 plates remain valid on vehicles registered before the switch and are still seen daily on the road.

NSW plate strings carry no regional signal. A plate issued in Broken Hill looks identical, in shape, to one issued in Wollongong or in inner Sydney — the registration office that printed the plate is not encoded in the characters. Personalised and "MyPlates" combinations, sold under the Transport for NSW concession to a private operator, sit alongside the standard series and may use bespoke colours, fonts, or short strings; those are out of scope for the standard validator and render as their own format class. Heavy vehicles, caravans, and motorcycles each have parallel sequences with their own letter or digit conventions, but the passenger-car ABC-12D shape is what you will see on the overwhelming majority of cars on a NSW road today.
